Walkden lost in the quarter-finals, but earned enough points to guarantee Britain an Olympic +67kg berth.

The season-ending event in Mexico City was the last opportunity for fighters to secure the top-six world ranking that would secure their nation a Rio place - something Briton Lutalo Muhammad achieved with -80kg victory on Saturday.

Earlier this year, many in the sport thought Walkden would struggle to qualify having suffered a serious knee-ligament injury in 2014.

However, the European champion won the World Championship in May and climbed to world number two after Grand Prix success.
